ORA-00214: control file '+DATA02_R5/fdmn1i/controlfile/current.265.799827461' version 6909395 inconsistent with file '+ARCH02_R5/fdmn1i/controlfile/current.11120.826208033' version 6909384

We already know about the reason but my overconfidence spoil around 1 hr for this error in RAC environment. Simple explanation is needed here '+DATA02_R5/fdmn1i/controlfile/current.265.799827461'
scn is 6909395 and other controlfile '+ARCH02_R5/fdmn1i/controlfile/current.11120.826208033' not able to write the changes after scn 6909384. So we need to need the recreate second
controfile as well. Please follow the below steps.

1)Add the Controlfile Entry Using spfile.
